We describe the novel occurrence of a adenocarcinoma involving the trachea, with distinct solid and glandular components, in a 34-year-old patient. We illustrate its morphological and immunophenotypic features and describe the molecular finding of an EWSR1::BEND2 gene fusion detected by next-generation sequencing (NGS). We discuss the findings in comparison to BEND2-fusion associated neoplasms reported in the head and neck region in the literature to date.

Introduction: Despite efforts to achieve health care equality, racial/ethnic disparities persist in lung cancer survival in the United States, with non-Hispanic Black patients experiencing higher mortality compared with non-Hispanic Whites. Previous research often focused on single treatments, overlooking the broad range of options available. We aimed to highlight disparities in survival and receipt of comprehensive lung cancer treatment by developing a guideline-concordant initial treatment (GCIT) indicator based on disease stage and recommended treatment.

Article Synopsis
  • National guidelines recommend segmental colectomy for appendiceal neuroendocrine neoplasms larger than 2.0 cm due to risks of lymph node involvement, with conditional overall survival becoming an important prognostic tool.
  • A study of 3,541 patients revealed that 16% had positive lymph nodes, and factors like size, depth of invasion, and lymphovascular involvement were correlated with metastasis.
  • The findings suggest that more clinicopathologic factors should influence decisions on surgical treatment and surveillance for better survival rates, especially for patients with more aggressive histologies.

Does the stop-signal P3 reflect inhibitory control?

Cortex

December 2024

Department of Psychological and Brain Sciences, University of Iowa, Iowa City, IA, USA; Department of Neurology, University of Iowa Hospitals and Clinics, Iowa City, IA, USA; Cognitive Control Collaborative, University of Iowa, Iowa City, IA, USA. Electronic address:

The ability to stop already-initiated actions is paramount to adaptive behavior. In psychology and neuroscience alike, action-stopping is a popular model behavior to probe inhibitory control - the underlying cognitive control process that is purportedly vital to regulating thoughts and actions. Starting with seminal work in the 1990s, the frontocentral stop-signal P3 - an event-related potential derived from scalp EEG - has been proposed as a neurophysiological index of inhibitory control during action-stopping.

Background: Most postgraduate medical education tracks are faculty-led and emphasise teaching skills. A peer-to-peer medical education track focused on curriculum development and scholarship is notably underrepresented in the literature, especially within graduate medical education. To address these gaps, a 2-year Distinction in Medical Education (DIME) track was developed.

Background: The prevalence of idiopathic intracranial hypertension (IIH) is rising with the global obesity epidemic. Carbonic anhydrase inhibitors (CAIs), such as acetazolamide, have been shown to be effective in IIH but can also lead to kidney stone formation. This study evaluates the risk of kidney stone development in patients with IIH treated with CAIs.

Immunometabolism in the Aging Heart.

J Am Heart Assoc

January 2025

Department of Radiation Oncology University of Iowa Hospitals and Clinic, University of Iowa Healthcare Iowa City IA USA.

Structural, functional, and molecular-level changes in the aging heart are influenced by a dynamic interplay between immune signaling and cellular metabolism that is referred to as immunometabolism. This review explores the crosstalk between cellular metabolic pathways including glycolysis, oxidative phosphorylation, fatty acid metabolism, and the immune processes that govern cardiac aging. With a rapidly aging population that coincides with increased cardiovascular risk and cancer incidence rates, understanding the immunometabolic underpinnings of cardiac aging provides a foundation for identifying therapeutic targets to mitigate cardiac dysfunction.

Electronic address:

Article Synopsis
  • Chemo-resistance is a major challenge in cancer therapy, and NRF1 and NRF2 are important in how cells handle oxidative stress, affecting tumor growth and drug resistance.
  • The study examines how NRF2 functions differently in normal and cancer cells, supporting cancer survival while protecting healthy cells.
  • It suggests that targeting the NRF signaling pathways could lead to new treatments that improve the effectiveness of chemotherapy against resistant tumors.

Background: Complete clot ingestion (CCI) is defined as full ingestion of the clot into the catheter or pump canister without any external clot remnants at the catheter tip. The aim of this study was to demonstrate that using the CCI metric in vitro, partially ingested ('corked') clots pose a higher risk of distal emboli given distal emboli may exist in the setting of Thrombolysis In Cerebral Infarction 3 (TICI 3) revascularization.

Methods: Thrombectomies using an in vitro synthetic clot analog were conducted across six catheters using the novel ALGO Smart Pump with Adaptive Pulsatile Aspiration (APA) (Von Vascular Inc, Sunrise, FL) and compared against the Penumbra static Engine Pump (Alameda, CA).

Background/objectives: Overall survival for patients with Stage 3 pancreatic ductal adenocarcinoma (PDAC) remains limited, with a median survival of 12 to 15 months. Irreversible electroporation (IRE) is a local tumor ablation method that induces cancerous cell death by disrupting cell membrane homeostasis. The DIRECT Registry study was designed to assess the effectiveness and safety of IRE when combined with standard of care (SOC) treatment for Stage 3 PDAC versus SOC alone in a real-world setting after at least 3 months of induction chemotherapy; Methods: Patients with Stage 3 PDAC treated with IRE plus SOC or SOC alone were prospectively enrolled in a multicenter registry study.

Purpose: Oral mucositis (OM) is a debilitating side effect of cisplatin and intensity-modulated radiation therapy (IMRT) in patients with head and neck cancer. The phase 3 ROMAN trial showed avasopasem manganese (AVA) significantly decreased individual endpoints of incidence and duration of severe oral mucositis (SOM, World Health Organization [WHO] grade 3-4), with nominal decrease in severity (WHO grade 4) and significant increase in the delay in onset of SOM. We sought to determine the Net Treatment Benefit (NTB) of AVA versus placebo (PBO) using the generalized pairwise comparisons (GPC) method.

Quantitative dynamic contrast-enhanced (DCE) MRI as a promising method for the prediction of breast cancer response to neoadjuvant chemotherapy (NAC) has been demonstrated mostly in single-center and single-vendor platform studies. This preliminary study reports the initial experience in implementing quantitative breast DCE-MRI in multi-center (MC) and multi-vendor platform (MP) settings to predict NAC response. MRI data, including B mapping, variable flip angle (VFA) measurements of native tissue R (R), and DCE-MRI, were acquired during NAC at three sites using 3T systems with Siemens, Philips, and GE platforms, respectively.

Neurocardiology: Major mechanisms and effects.

J Electrocardiol

January 2025

Carver College of Medicine, University of Iowa Hospitals and Clinics, Iowa City, IA, United States of America.

Neurocardiology is a broad interdisciplinary specialty investigating how the cardiovascular and nervous systems interact. In this brief introductory review, we describe several key aspects of this interaction with specific attention to cardiovascular effects. The review introduces basic anatomy and discusses physiological mechanisms and effects that play crucial roles in the interaction of the cardiovascular and nervous systems, namely: the cardiac neuraxis, the taxonomy of the nervous system, integration of sensory input in the brainstem, influences of the autonomic nervous system (ANS) on heart and vasculature, the neural pathways and functioning of the arterial baroreflex, receptors and ANS effects in the walls of blood vessels, receptors and ANS effects in excitable cells in the heart, ANS effects on heart rate and sympathovagal balance, endo-epicardial inhomogeneity, ANS effects with a balanced vagal and sympathetic stimulation, sympathovagal interaction, arterial baroreflex, baroreflex sensitivity and heart rate variability, arrhythmias and the arterial baroreflex, the cardiopulmonary baroreflex, the exercise pressor reflex, exercise-recovery hysteresis, mental stress, cardiac-cardiac reflexes, the cardiac sympathetic afferent reflex (CSAR), and neuromodulation.
